Lots of stuff going on behind the scenes to make it easier to administer players, but not much visible yet. One small thing did go out just now: The "Identities" tab. You'll find it here: https://matchplay.events/live/users/identities
It lists all the players you have "claimed" under different tournament organizers. Use it to double-check you didn't claim to be someone else by accident. MP will also attempt to guess any unclaimed players from tournaments past (based on your name) so you can claim them.
On the front page of MP Live you will see this message if MP thinks you should go claim some old players:
I hope you will encourage your friends to go claim their old players because I'm working on head-to-head results statistics and they'll be a lot better if MP knows who you really are!
